Visible crew/equipment: By the tidal pool, Magnum mentions ESP and says "I am not laughing", crouching down. Following his movement, a boom mike gets lower as well, thus getting in frame. (00:07:45)
Audio problem: When she comes around at King Kamehameha and especially in the scene by the tidal pool, Rebecca Holden's lines are very noticeably dubbed in.
Continuity mistake: When Rick sits by Magnum and Laura, he puts his left hand on the armrest. It's the whole forearm in the next shot. (00:05:15)
Continuity mistake: In the initial phase of the conversation over the phone (and the road) with Agent John W. Newton, Eric Tobin's hand shifts slightly on the microphone between shots (the position of his index is different), and in a much more evident flub, when he says twice "Delta One" at the very end he has no left hand at all on the phone receiver in the first shot, and does in the second. (00:03:00)
Audio problem: When Tobin receives the call from across the street, the agent in the long shot is talking without moving his lips. (00:02:25)
